I saw the movie The Social Network tonight, here are my spoiler-free comments.
The movie was incredibly well made. Aaron Sorkin's writing was as good as the best days of The West Wing, each member of the cast seemed to just nail their role, the editing was some of the best I've seen, and so on.
Perhaps most enjoyably, this is a mainstream movie that is at least in part about the culture and goings-on in the modern world of Internet entrepreneurship, I believe the first of its kind. It fully embraces the geekiness that was and is a part of building a web application like Facebook: in the first 30 minutes, the Apache webserver software project is mentioned at least twice, there are dramatic lines about needing more Linux webservers running MySQL, there are punchlines that involve the emacs text editor, and scenes of glorious code writing marathons - wow.
